ISC BIND

BIND (Berkeley Internet Name Domain) is an implementation of the Domain Name System (DNS) protocols and provides an openly redistributable reference implementation of the major components of the Domain Name System, including:

The BIND DNS Server is used on the vast majority of name serving machines on the Internet, providing a robust and stable architecture on top of which an organization's naming architecture can be built. The resolver library included in the BIND distribution provides the standard APIs for translation between domain names and Internet addresses and is intended to be linked with applications requiring name service.

BIND4/BIND8
Unsuitable for Forwarder Use

If a nameserver -- any nameserver, whether BIND or otherwise -- is configured to use ``forwarders'', then none of the the target forwarders can be running BIND4 or BIND8. Upgrade all nameservers used as ``forwarders'' to BIND9 . There is a current, wide scale Kashpureff-style DNS cache corruption attack which depends on BIND4 and BIND8 as ``forwarders'' targets.

See the BIND Security Matrix for security-related information.
